Nānā nui  

Hoʻokaʻawale ka G.703 (Co-Directional G.703) i ka pōʻaiapuni 64Kbps i 4 mau kikowaena, hoʻohana ʻo ia i ka "0101" e hōʻike ana i ka "0", "1100" e hōʻike ana i ka "1". Ma ka hoʻololi ʻana i ka polarity o ka poloka pili, hoʻololi nā hōʻailona binary i nā hōʻailona pae ʻekolu. I kēlā me kēia hui 8 i luku ʻia ka poloka o ka polarity ʻokoʻa, no laila e hoʻouna i ka hōʻailona manawa 8KHz. Ma ka coding i luna, hiki i ka G.703 co-directional 64Kbps hōʻailona ke hoʻokō i ka hoʻouna ʻana i ka hōʻailona manawa o 64KHz a me 8KHz a me 64KHz a me ka hōʻailona ʻikepili o 64Kbit/s ma ka ʻaoʻao like me kahi laina kaulike pālua.
64k-RS232/422 / 485 mea hoʻololi hoʻololi i hāʻawi iā ITU-T co-64K G.703 maʻamau E1 interface a me RS232 / 422/485 maʻamau hoʻololi ma waena o ka papa kino. Pūnaewele e hāʻawi i nā kamaʻilio paʻa ma waena o nā polokalamu o nā ʻokoʻa like ʻole, ka pilina paʻa ʻole. He kūpono no ka hoʻouna ʻana i nā ʻāpana ʻāpana E1 i loaʻa, a me nā mea pono e hoʻololi i ka ʻikepili a me nā manawa puka RS232 / 422/485 wale nō.
